Method for transmitting and receiving sidelink signal in wireless communication system

Abstract

An aspect of the present disclosure is a method for user equipment in a wireless communication system, wherein a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) are received on an aggregation slot including a plurality of slots, and a sidelink signal is transmitted on a resource selected on the basis of at least one among a reference signal received power (RSRP), a received signal strength indication (RSSI), and a reference signal received quality (RSRQ), which are measured from the aggregation slot. The RSRP is measured from each of slots, on which a plurality of PSCCHs are received, among the plurality of slots on the basis of the plurality of PSCCHs being received on the aggregation slot.

The invention claimed is: 
     
       1. A method of a first user equipment (UE) in a wireless communication system, the method comprising:
 configuring a resource pool for communication with a second UE; 
 receiving control information from the second UE; and 
 receiving data based on the control information from the second UE, wherein: 
 the control information includes information for a first resource set and a second resource set in the resource pool, and the first resource set includes an aggregation slot configured with consecutive slots and the second resource set includes a non-aggregation slot configured with one slot; 
 the control information being received in each of the consecutive slots; 
 based on a priority of the data being above a threshold, a resource for the data is selected from the first resource set based on a maximum value of reference signal received powers (RSRPs) measured from the each of the consecutive slots; and 
 based on there being no resource within a remaining latency budget in the first resource set, a resource for the data within the remaining latency budget is selected from the second resource set. 
 
     
     
       2. An apparatus for a first user equipment (UE) in a wireless communication system, the apparatus comprising:
 a transceiver; 
 at least one processor connected to the transceiver; and 
 at least one memory operatively connected to the at least one processor and configured to store at least one instruction for allowing the at least one processor to perform operations, wherein: 
 the processor configures a resource pool for communication with a second UE, receives control information from the second UE, and receives data based on the control information from the second UE; 
 the control information includes information for a first resource set and a second resource set in the resource pool, and the first resource set includes an aggregation slot configured with consecutive slots and the second resource set includes a non-aggregation slot configured with one slot; 
 the control information being received in each of the consecutive slots; 
 based on a priority of the data being above a threshold, a resource for the data is selected from the first resource set based on a maximum value of reference signal received powers (RSRPs) measured from the each of the consecutive slots; and 
 based on there being no resource within a remaining latency budget in the first resource set, a resource for the data within the remaining latency budget is selected from the second resource set. 
 
     
     
       3. A processor for performing operations for a first user equipment (UE) in a wireless communication system, the operations comprising:
 configuring a resource pool for communication with a second UE; 
 receiving control information from the second UE; and 
 receiving data based on the control information from the second UE, wherein: 
 the control information includes information for a first resource set and a second resource set in the resource pool, and the first resource set includes an aggregation slot configured with consecutive slots and the second resource set includes a non-aggregation slot configured with one slot; and 
 the control information being received in each of the consecutive slots; 
 based on a priority of the data being above a threshold, a resource for the data is selected from the first resource set based on a maximum value of reference signal received powers (RSRPs) measured from the each of the consecutive slots; and 
 based on there being no resource within a remaining latency budget in the first resource set, a resource for the data within the remaining latency budget is selected from the second resource set.
